Didn't they also say something to the effect of "aaah, SAM is fine, for you see, DRG brings party utility that makes its damage contribution up to par"?
That's a bit worrying, as the 5k parses of each EX primal we have to work with heavily suggest otherwise- it also compounds this issue that one of the prime recipients of DRG's piercing debuff, MCH, is both underpowered and slightly undesired atm.
Oh my. My heart goes out to you, my DRG and MCH brothers and sisters x)
